uniquevals

Since	17.0

int [] uniquevals(<geometry>geometry, string attribclass, string attribute_name)

string [] uniquevals(<geometry>geometry, string attribclass, string attribute_name)

If any points/primitives/vertices in the geometry have the same value for the given attribute, the set of unique values will be smaller than the total number of points/primitives/vertices. This function lets you acquire the set of unique values.

This function only works with string and integer attributes.

<geometry>

When running in the context of a node (such as a wrangle SOP), this argument can be an integer representing the input number (starting at 0) to read the geometry from.

Alternatively, the argument can be a string specifying a geometry file (for example, a .bgeo) to read from. When running inside Houdini, this can be an op:/path/to/sop reference.

attribclass

One of "detail" (or "global"), "point", "prim", or "vertex".

You can also use "primgroup", "pointgroup" or "vertexgroup" to read from groups.

attribute_name

The name of the attribute (or intrinsic) to read.
